HP takes a structural, yet synergic, approach every time we innovate. Parallelly, lines guide the eye to reveal what’s next.
Use horizontal divider lines to separate content from top to bottom, different sections or ideas, or items in a list, such as product specs.
Divider lines should run edge to edge of the layout or section (with the exception of lists).
Use lines to separate headline-only layouts, lists, quotes, multiple lines of content. Note, not all layers of text need lines.
